Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and hydropower engineering technology, and relates to a pipeline installation equipment for water conservancy and hydropower construction. Background Technology

[0002] Water is a precious resource essential for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production.

[0003] In pipe gallery construction, multiple pipe sections are typically welded together end to end to form a longer pipeline. Before welding, the joints of adjacent pipe sections need to be aligned and fixed. Traditional alignment is usually done manually by moving the two pipe sections, which is difficult and ineffective; moreover, the alignment process is cumbersome, takes a long time to adjust, and rarely achieves the desired result in one step.

[0004] To address the aforementioned problems, this utility model proposes a pipeline installation device for water conservancy and hydropower construction. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes a road and bridge maintenance device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a pipeline installation device for water conservancy and hydropower construction, including an operating platform and centering mechanisms located on the left and right sides of the operating platform. Two adjacent pipelines are respectively placed on the left centering mechanism and the right centering mechanism. The positions of the two adjacent pipelines are adjusted by the two centering mechanisms, and the centering operation is performed on the operating platform.

[0007] Furthermore, the centering mechanism includes a support base, a mobile locomotive, and a centering and straightening assembly; the mobile locomotive is installed on the side of the support base away from the operating table and can push the pipeline along the support base toward the operating table; the centering and straightening assembly is installed on both sides of the support base and can center the pipeline.

[0008] Furthermore, a guide rail is installed on the support base along its length, and guide wheels adapted to the guide rail are installed on the mobile locomotive.

[0009] Furthermore, a rack is installed on the support base along its length, and a drive motor adapted to the rack is installed on the mobile locomotive.

[0010] Furthermore, the mobile locomotive is equipped with pipe clamps for pipe alignment.

[0011] Furthermore, the pipe clamp includes a three-jaw chuck mounted on a mobile locomotive.

[0012] Furthermore, the centering assembly includes at least one set of centering components, with the same set of centering components symmetrically arranged along the front and rear of the support base; the pipe is clamped by the same set of centering components.

[0013] Furthermore, the centering correction component includes a centering cylinder, a centering roller assembly, and a mounting bracket; the centering roller assembly is mounted on the mounting bracket, the mounting bracket is mounted on the piston rod of the centering cylinder, and the centering cylinder is mounted on a support base.

[0014] Furthermore, the support base is equipped with guide strips along its length.

[0015] Compared with existing technologies, this invention has the following advantages: In this invention, the operator places the two pipes to be connected or welded on the left and right centering mechanisms respectively. The two adjacent pipes are first aligned onto the same axis using the left and right centering mechanisms. Then, the left centering mechanism moves the left pipe to the right, bringing its right end onto the operating table. Simultaneously, the right centering mechanism moves the right pipe to the left, bringing its left end onto the operating table. This continues until the right ends of the left and right pipes are in the appropriate positions, at which point the operator performs the welding operation on the operating table. During this process, no manual pipe movement or centering is required, saving time and effort while ensuring precise centering. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-3 As shown, the technical solution adopted by this utility model is as follows: A pipeline installation device for water conservancy and hydropower construction includes an operating platform 1 and centering mechanisms 2 located on the left and right sides of the operating platform 1. Two adjacent pipelines are respectively placed on the left centering mechanism 2 and the right centering mechanism 2. The positions of the two adjacent pipelines are adjusted by the two centering mechanisms 2, and centering is performed on the operating platform 1. The operator places the two pipelines to be connected or welded on the left centering mechanism 2 and the right centering mechanism 2, respectively. The two adjacent pipelines are first adjusted to be on the same axis by the left centering mechanism 2 and the right centering mechanism 2. Then, the left centering mechanism 2 moves the left pipeline to the right, so that the right end of the left pipeline moves to the operating platform 1. At the same time, the right centering mechanism 2 moves the right pipeline to the left, so that the left end of the right pipeline moves to the operating platform 1, until the right end of the left pipeline and the left end of the right pipeline are adjusted to the appropriate position. The operator then performs welding operations on the operating platform 1. During this process, there is no need for manual pipeline movement or manual centering, saving time and effort, and ensuring accurate centering.

[0022] In this embodiment, the centering mechanism 2 includes a support base 21, a moving trolley 22, and a centering and straightening assembly 23. The moving trolley 22 is installed on the side of the support base 21 away from the operating table 1 and can push the pipe along the support base 21 toward the operating table 1. The centering and straightening assembly 23 is installed on both sides of the support base 21 and can center the pipe. After the pipe is placed on the support base 21, the centering and straightening assembly 23 first performs a centering operation on the pipe to ensure that the two pipes on the two centering mechanisms 2 are on the same axis. Then, the moving trolley 22 pushes the pipe toward the operating table 1 until the right end of the left pipe and the left end of the right pipe are adjusted to the appropriate position, and the operator performs welding operations on the operating table 1.

[0023] In this embodiment, a guide rail 3 is installed on the support base 21 along its length direction, and a guide wheel adapted to the guide rail 3 is installed on the mobile locomotive 22; the guide rail 3 and the guide wheel cooperate to ensure that the mobile locomotive 22 drives the pipeline to run stably.

[0024] In this embodiment, a rack 4 is mounted on the support base 21 along its length, and a drive motor adapted to the rack 4 is mounted on the mobile trolley 22. The drive motor is a conventional stepper motor, and a gear adapted to the rack 4 is mounted on the output shaft of the stepper motor. The stepper motor's rotation speed is controlled by a controller, thereby controlling the movement distance of the mobile trolley 22 on the support base 21, thus adapting to pipes of different lengths.

[0025] In this embodiment, a pipe clamp for pipe alignment is installed on the mobile locomotive 22. The pipe clamp includes a three-jaw chuck 5 mounted on the mobile locomotive 22. When the alignment and centering assembly 23 performs the pipe alignment operation, the three-jaw chuck 5 clamps the pipe to prevent pipe displacement and ensure stable welding of adjacent pipes.

[0026] In this embodiment, the centering and alignment assembly 23 includes at least one set of centering and alignment members, which are symmetrically arranged along the front and rear of the support base 21. The centering and alignment members in the same set clamp the pipe. When the pipe is placed on the support base 21, it automatically returns to center under the action of the centering and alignment members, thereby ensuring that the pipes on the two alignment mechanisms 2 are on the same axis.

[0027] In this embodiment, the centering device includes a centering cylinder 23a, a centering roller assembly 23b, and a mounting bracket 23c. The centering roller assembly 23b includes multiple rollers, which are mounted side-by-side vertically on the mounting bracket 23c. The mounting bracket 23c is bolted to the piston rod of the centering cylinder 23a. The centering cylinder 23a is mounted on a support base 21 and is connected to an external air source. When the pipe is placed on the support base 21, the centering cylinder 23a pushes the centering roller assembly 23b toward the outer wall of the pipe. The two centering roller assemblies 23b in the same group press against the outer wall of the pipe. Since the rollers can rotate independently, the pipe returns to center during the pressing process of the two centering roller assemblies 23b, preventing the pipe from shifting.

[0028] In this embodiment, a guide bar 6 is installed on the support base 21 along its length. When the mobile locomotive 22 pushes the pipeline, the guide bar 6 plays a guiding role.

[0029] When using this device, two adjacent pipes are placed on the centering mechanisms 2 on the left and right sides respectively. The same set of straightening and centering parts in the left and right centering mechanisms 2 clamp the pipes, thereby centering them. Then, the three-jaw chuck 5 clamps the tail end of the pipe, and the moving trolley 22 pushes the left centering mechanism 2 to move the left pipe to the right, so that the right end of the left pipe moves onto the operating table 1. At the same time, the right centering mechanism 2 moves the right pipe to the left, so that the left end of the right pipe moves onto the operating table 1. This continues until the right end of the left pipe and the left end of the right pipe are adjusted to the appropriate position. The operator then performs welding operations on the operating table 1.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
